Maxim Integrated MAX6314US44D4-T Microprocessor Reset Circuit

The Maxim Integrated MAX6314US44D4-T is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant line of defense against system failures caused by fluctuations in the power supply or other unexpected system faults. This component is particularly suitable for portable, battery-operated applications due to its low power consumption and small footprint.

This supervisory circuit ensures that the µP starts up in a known state by asserting a reset signal whenever the VCC supply voltage declines below a preset threshold. The reset output remains asserted for a period after VCC has risen above the reset threshold, allowing the power supply and processor to stabilize before the system startup. The reset delay period, in this case, is internally set to a standard 4.16ms minimum, ensuring consistent and reliable performance without the need for external components.

The MAX6314 series offers factory-set VCC reset thresholds suitable for a wide range of applications. The MAX6314US44D4-T variant specifically has a reset threshold of 4.40V, which is tailored for systems operating around a 5V supply. The device operates with a supply voltage range from 1.2V to 5.5V, catering to a variety of logic levels and power requirements.

Enclosed in a compact SOT-143 package, the MAX6314US44D4-T is designed for space-constrained applications. It features a manual reset input that allows a reset to be triggered with an external switch or another control element, providing additional system management flexibility. The active-low, open-drain RESET output ensures compatibility with a variety of digital systems.

Maxim Integrated's commitment to quality ensures that the MAX6314US44D4-T supervisory circuit is a reliable choice for maintaining system integrity. This makes it an ideal choice for microprocessor systems, computers, controllers, and intelligent instruments that require precise monitoring and control of the power supply to safeguard system operation.

Overall, the MAX6314US44D4-T is an essential component for designers looking to enhance system reliability and prevent data corruption due to undesirable power supply conditions in their digital systems.
